Tease band releasing second disc (4)

I believe the answer is:

comb

I'm a little stuck... Click here to teach me more about this clue!

'tease' is the definition.
(I know that tease is a more specific form of the action comb)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for comb that I've seen before include "Carefully search" , "Groom the tresses" , "Disentangle" , "Device for tidying one's appearance" , "Fastening spikes" .)

I've seen this clue in The Times and The Guardian.
